Hi List, I have a postfix server based on CentOS 5 in which I have been trying to add TLS encryption support for SMTP. From the localhost when I do an EHLO, following is the output [root at xxxxxxx ~]# nc localhost 25 220 xxxxxxx.xxxx.xxx.xx ESMTP Postfix EHLO localhost 250-xxxxxxx.xxxx.xxx.xx 250-PIPELINING 250-SIZE 41943040 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN

Hello, I'm setting up Dovecot 2.3.2.1 as a submission proxy to a Postfix backend server. Dovecot announces CHUNKING, but the Postfix backend does not support (or announce) it. HELO from Postfix: 220 backend.mydomain.com ESMTP Postfix (Ubuntu) ehlo test 250-backend.mydomain.com 250-PIPELINING 250-SIZE 104857600 250-VRFY 250-ETRN 250-STARTTLS

I am sending an email from my machine devcentos5x64. the transcript below (hangs for 60 seconds) at the line: MAIL From:<root at devcentos5x64.msgnet.com> SIZE=56 AUTH=root at devcentos5x64.msgnet.com The email succeeds - but I am trying to figure out the 60 second delay. Neither email server is busy. Nothing is waiting. the DNS on both machines point to the same nameserver. The DNS

Hi I have installed the package dovecot-postfix on Ubuntu 12.04 LTS: dovecot --version: 2.0.19 postconf -d | grep version: 2.9.6 and receiving email works very fine, but relaying email does not work. I think the problem is that after STARTTLS the authentication is not being executed 250-AUTH PLAIN 250-AUTH=PLAIN which means using telnet returns telnet mx2.wyona.com 587 Trying

Hello folks, I have a CentOS 6.4 installation running Sendmail, and after some serious hair tear stare and compare I'm a bit stumped. When I connect to the server either with telnet or SSL, sendmail is not presenting the AUTH capability after an EHLO. Everything looks like it should be working, but no amount of tweaking is getting the AUTH capability advertised (and it doesn't work if

Hi, With latest 2.3 -git (and 2.3.0 release), I'm running into this error with Thunderbird: "An error occurred while sending mail. The mail server responded: 5.5.4 Unsupported mail BODY type. Please verify that your email address is correct in your account settings and try again." This is fatal and means Thunderbird cannot use the submission service - fortunately I can revert

This should be an easy one. I'm trying to get postfix going. I've never done this before. I followed the directions at http://wiki.centos.org/HowTos/postfix. I opened port 25: iptables -I INPUT -p tcp -m tcp --dport 25 -j ACCEPT Here's an attempt to send mail: [motor at localhost motor]# mail -v larry.martell at gmail.com Subject: test test . EOT larry.martell at gmail.com...

Hello, I'm having trouble configuring the submission proxy. I have configured the submission service as follow: submission_host = smtp.example.com submission_relay_host = localhost submission_relay_port = 8587 submission_relay_rawlog_dir = /var/log/dovecot/ submission_relay_trusted = yes My main issue is that until I login, dovecot-submission won't connect to the backend and query the

Folks I am using sendmail as my mail server. SELINUX is disabled. I observe messages in Centos 7 (and 6) in /var/log/messages, similar to: saslauthd[2765]: do_auth : auth failure: [user=bettie] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error] I guess that this is because somebody tried to access one of the SMTP ports with a logon attempt. This is understandable; there are

Hi, I am using dovecot with postfix for authentication. Everything (TLS/SSL, authentication) is working fine, except that when I set: disable_plaintext_auth = yes I still can authenticate with plain text on a no TLS/SSL session: 20 mail2.cs.ait.ac.th ESMTP Postfix (2.6.2) EHLO [192.41.170.57] 250-mail2.cs.ait.ac.th 250-PIPELINING 250-SIZE 10240000 250-VRFY

I asked a user today to make sure his incoming and outgoing email was using TLS. He told me it wasn't possible because my Dovecot / Postfix daemons were only listening on TCP 25 & 143 according to a port scan he did. He told me the only way I could enable encrypted secure sessions between the client & server is to enable port 993 (IMAPs). I told him that TLS is supported on my mail
